Codelco (Corporación Nacional del Cobre) is the Chilean state-owned copper mining company, formed in 1976 from the nationalized mines of Chuquicamata, El Teniente, and others. It has since become the world's largest copper producer, facing challenges from aging mines, labor disputes, and environmental regulations while expanding globally.
The Chuquicamata copper mine, owned by the Chile Exploration Company (a subsidiary of Anaconda Copper), starts large-scale open-pit mining. It becomes one of the world's largest copper mines. #mining #copper
